Be it known that I, EPHRAIM HOWLAND, a citizen of the United States,residing at Pontiac, county of Oakland, State of Michigan, have inventeda certain new and useful Improvement in Loading, Conveying, and DumpingDevices; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to improvements in portable loading and dumpingmachines orv conveyances for loading and carrying dirt,

sand, gravel, manure, and other like mate-.

tongue and means for guiding the front wheels are omitted. Fig. 2 is aplan View. Fig. 3 is a front elevation. Fi 4 is a view of the Windlassand engine connections.

Similar letters refer to similar parts.

A A represent the sills of the body proper; WW, the wheels upon whichthe same is con- Veved.

B B are the sides, which otherwise, except as being rights and lofts,are similar in construction and are solidly built up from the "sills AAby means of vertical posts and side boards in the usual manner. Acri-iss-parlition (7 sci'mratcs the space inclosed by the sides B B intotwo parts, the partition being The two spaces into which the contentsbetween the side pieces B it are thus divided by the partition (3 areopen at both front and rear. The front portion is lloorcd at 1), whereasthe rear portion is open, except when closed by means of the unloadingdevices hereinafter to be described. Upon the floor l) is mounted anordinary gas-engine IQ of the requisite power, possessing all of itsusual appliances and carrying upon its sha'l't a band-pulley e.

thereby until an idler-pulley H tightens the band in the usual way bymeans of a bent handlever H. The Windlass F-is not only revolublymounted on the shaft G, but is slidably mounted thereon, and when, asshown in Fig. 3, it is m Vlid to the left it'can revolve freely n 7011saill but when mover to the right a clutch engagement, such as pin g,engaging in a notch 9 will compel the Windlass to revolve with theshaft, and thus be driven by the band-wheel G,fixed upon the shaft whenthe belt is tightened. A rope J, one end of which is fixed to theWindlass F and partially or wholly wound thereon, is operated by theWindlass F and used as hereinafter descril. cd.

As the construction of the gas-engine and the Windlass proper, asidefrom the details hereinbefore given, is common to such engines andhoisting devices, it is unnecessary to further describe them or toillustrate them.

Pivotally attached to the rear end of the main frame at a is a bridgeadapted to be raised and lowered in the manner hereinafter described andforming a' device for loading in connection with the scraper A", whichmay be drawn by the rope J up the bridge and, if desired, to the frontend of the rear compartment adjarentto partition t. The bridge hastriangularly-formed sides (1. a, with triangularly-formed telescope endsa), which when the bridge is raised, as hereinafter dc scribed, passinside ol' the sides B if and when the bridge is lowered close off anyopening that would otherwise exist. Upon one end, adjacent to the pivot(Mil the bridge A, is a gullows'frame consisting of two upright posts,one upon either side, with a cross-bar lirmly attached thereto at thetop. .lropcr braces (1 connect the sides of the frame with the triangulur sidc pieces (.L 1. thereby rend-cring the whole structure rigid. Theside pieces (1 a have terminal wings a", which are llared outwardly, asshow u in the plan view. Also the outer edge of the bridge A is madesharp at (L and preferably bound with iron, and when the apparatus is inplace for loadshaft as a bearing;

ing'and the bridge dropped to the ground the edge naturally digs intothe ground and the bridge forms a brace, whereby the backward movementof the apparatus is predump-board is pivoted u on an iron crossbarpassing underneat the same and a short distance from its front end, forthe reason hereinafter stated, and is raised and loweredthe mannerhereinafter to be described. As shown. in the plan view, Fig. 2, thereare two similar dump-boards K K", also pivoted on round iron pivots 7rA. All of these three dump-boards are held in position, forming a bottomto the box or dirt-receptacle, by means of the a paratus hereinafterdescribed. In view of keeping the body as low as possible and yet givingthe dumpboards the re uisite inclination for depositing theload, t epivot-bars upon which they 'turn are located back fromthe front edge ofthe dump-boardssay, comparatively, from one fourth to. one-third oftheir length, or at a point sufficiently far to insure the heavier endwith its load overhalancing the lighter end and its load, thus securinga rompter delivlie greater inclinatlon thus secured. This is quiteimportant with the dump board in the bridge, be-

- cause the bridge must be long enough to assure an easy ascent and alsopreferably long" enough to carry a considerable load, as this loadbalances the load forward of the rear axle and enables much more of tobe carried upon the rear axle, which is desirable. As the bridge,therefore, is long, comparatively,

dropping the brid e itself would not insure prompt delivery of the load.Therefore the dump-board is pivoted back of its front edge for thepurpose of securing ,an inclination requisite for delivering the load. Ashaft M is j ournaled upon either side of the sides B B and iscontrolled by a handle m, partially cut away, and has upon either sidecranks m m. At-

tached to the outer end of these cranks are ropes m, passing overpulleys m and firmly attached to the outer end of the dump-board K at mby means of acrossiece extending beyond the sides A of the bridge or thesills.

As shown in Fig. l, the dump-board K is closed. Journaled. upon thefront end and top of the girths 6 b is a shaft N, carrying duplicatecranks n it and controlled by lever n. A rope connects the outer end ofthe cranks n -with cross-pieces attached to the dumpboard K, and, asshown in position in the drawings, the dump board K is shown closed. Inthe dotted lines in Fig. 1 the dump-board K is shown partially 0 en, theposition of the rope when the dump- I oarfd is thus open being a soshown in dotted lines.

It will be noted that when closed the of the crank n is past the center,so that t ey ull The operation using this'device' is as follows: Therope J, which may be of any assignable or reasonable length, is hookedinto the bail of'the scraper A and the drum F being allowed to revolvefreely the scraper is drawn to any position'which may be desired, thedrum being then clutched with the shaft G and the engine started, or ifthe enginebe still under motion, the idler H being thrown intoconnection with the band, the Windlass F is thereby operated to draw thescraper toward the bridge A, engagin whatever material is to be loaded.This is led and drawn to and up the bridge to thefront end of the rearcompartment'near the partition C and there dumped. I The Windlass isthen detached from the clutch-and .the scraper is drawn backforreloading, and the operation is repeated until the whole bodyis filled.Then the bridge itself is filled as far as possible, when by detachingthe hook of the rope from the hail of the scraper and attaching it tothe top of the'gallows-frame and operating the Windlass the bridge A canbe raised up to a level with the floor of the body and held there withits load during the transportation of the entire load to the place wherewanted. On arriving at the place where the load is to be dumped theshafts M and N are operated in the manner indicated and drop thedump-boards K, K, and K whereby the whole load is almost instantlydumped and the device drawn from over the dumped 'load to be returned tothe place for reloading.

It is obvious that many variations of details may bemade withoutdepartingfrom the principle of my invention. I

Ilaving thus described my invention, what I desire to claim is 1; In acombined loading conveying and dumping device, the combination of abodyv mounted upon traveling wheels, a motor.

mounted on the front end of said body, a Windlass to be operated by saidmotor, means for gathering a load operated by said Wind lass, abridgepivotally attached to" the rear end of said traveling device adapted tooper ate as a brace against the resistanc e of the loading pulls, and tobe raised whenl loaded, substantially as described.

2. In a combined loading, conveying'and dumping device, the combinationof a body adapted to travel upon wheels, motor means carried therebyadapted to draw the material to be loaded thereonto, a bridge pivoted tothe endfladapted to serve as a brace, and means connecting said bridgeand said motor means whereby the bridge may be hauled up and held inposition to support a part of the load during the movement of thevehicle, substantially as described.

3. In a combined loading conveying and dumping device, the combinationof a body adapted to travel upon wheels, means mounted thereon wherebythe material to be loaded can be drawn into and dumped upon the floorthereof, a bridge adapted to form a brace and also as means "forcontrolling the passage thereover of the loading means, the

ottom of said device and said bridge having dump-boards and means forcontrolling the same, substantially as described.

4. In a combined loading conveying and dumping device, in combinationwith the body mounted upon traveling wheels, a bridge pivotally attachedto the rear end of said body, means for raising and'lowering tilt thebridge, and a pivoted dump-board located in said bridge, affording whendropped an inclination of greater angle than the bridge when the same isdropped, and means for operating said dump-board, substantially asdescribed.

5;. In a combined loading, conveying and dumping device, the combinationof a bOL y 'member adapted to travel upon wheels, a

bridge memberpivoted to one end of said body member, du1np-boardspivoted to and forming a part of the floor portion of said members, saidboards being so adjusted that one end is raised while the other descends-under the influence of the load, and means carried by said body portionwhereby said boards may be raised and lowered, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.
